DYS 20A SimonK Multicopter Brushless ESC

A single 20A brushless speed controller from DYS, running SimonK's dedicated multicopter firmware for fast, precise throttle response. It suits classic multirotor builds such as F450 and S500-style quads or hexacopters, where each arm carries its own ESC driven by standard PWM from the flight controller.

Key features

• SimonK multicopter firmware on a master chip with a high-stability crystal oscillator for accurate motor timing
• High-power MOSFETs with a separate heatsink and a low-resistance PCB for strong current endurance
• Low-resistance power input that improves supply stability and is gentler on the battery
• Separate voltage regulator IC for the microprocessor, for better resistance to electrical noise
• Safe arming: the motor will not start on power-up, whatever the throttle stick position

Specifications

• Rated current: 20 A
• Firmware: SimonK (multicopter)
• Max motor speed: 210,000 RPM (2-pole), 70,000 RPM (6-pole), 35,000 RPM (12-pole)
• Configuration: Single ESC, one motor per unit

Order one per motor and calibrate the throttle range on all of them together before the first flight. Check the peak current of your motor and propeller combination at full throttle and keep it comfortably below 20 A.
